Abstract
A graft copolymer of: an organic solvent soluble fluoropolymer having at least one urethane linkage and containing at least one radically polymerizable bond; at least one polysiloxane having a radically polymerizable terminal group; at least one monomer having a radically polymerizable double bond and a fluoroalkyl group per monomer molecule; and at least one different radically polymerizable monomer. Compositions containing this graft copolymer composition are suitable for use as a coating having water repellent, oil repellent and stain resistant properties over a long period of time.
